Editable text fields should provide an `android:hint` or, provided your
`minSdkVersion` is at least 17, they may be referenced by a view with a
`android:labelFor` attribute.

When using `android:labelFor`, be sure to provide an `android:text` or
an `android:contentDescription`.

If your view is labeled but by a label in a different layout which
includes this one, just suppress this warning from lint.

!!! Tip
   This lint check has an associated quickfix available in the IDE.

(##) Example

Here is an example of lint warnings produced by this check:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text
res/layout/labelfororhint_empty_hint.xml:11:Warning: Empty android:hint
attribute [LabelFor]
    android:hint=""
    ---------------
res/layout/labelfororhint_empty_hint.xml:21:Warning: Empty android:hint
attribute [LabelFor]
    android:hint=""
    ---------------
res/layout/labelfororhint_empty_hint.xml:29:Warning: Empty android:hint
attribute [LabelFor]
    android:hint=""
    ---------------
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here is the source file referenced above:

`res/layout/labelfororhint_empty_hint.xml`:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~xml linenumbers
&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:orientation="vertical"&gt;

    &lt;EditText
            android:id="@+id/editText1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ems="10"
            android:hint=""
            android:inputType="textPersonName"&gt;
        &lt;requestFocus/&gt;
    &lt;/EditText&gt;

    &lt;AutoCompleteTextView
            android:id="@+id/autoCompleteTextView1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ems="10"
            android:hint=""
            android:text="AutoCompleteTextView"/&gt;

    &lt;MultiAutoCompleteTextView
            android:id="@+id/multiAutoCompleteTextView1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ems="10"
            android:hint=""
            android:text="MultiAutoCompleteTextView"/&gt;
&lt;/LinearLayout&gt;

found for this lint check, `LabelForDetector.testWithEmptyHint`.

(##) Suppressing

You can suppress false positives using one of the following mechanisms:

* Adding the suppression attribute `tools:ignore="LabelFor"` on the
  problematic XML element (or one of its enclosing elements). You may
  also need to add the following namespace declaration on the root
  element in the XML file if it's not already there:
  `xmlns:tools="http://schemas.android.com/tools"`.

  ```xml
  &lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;EditText xmlns:tools="http://schemas.android.com/tools"
      tools:ignore="LabelFor" ...&gt;
    ...
  &lt;/EditText&gt;
  ```

* Using a special `lint.xml` file in the source tree which turns off
  the check in that folder and any sub folder. A simple file might look
  like this:
  ```xml
  &lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;lint&gt;
      &lt;issue id="LabelFor" severity="ignore" /&gt;
  &lt;/lint&gt;
  ```
  Instead of `ignore` you can also change the severity here, for
  example from `error` to `warning`. You can find additional
  documentation on how to filter issues by path, regular expression and
  so on
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html).

* In Gradle projects, using the DSL syntax to configure lint. For
  example, you can use something like
  ```gradle
  lintOptions {
      disable 'LabelFor'
  }
  ```
  In Android projects this should be nested inside an `android { }`
  block.

* For manual invocations of `lint`, using the `--ignore` flag:
  ```
  $ lint --ignore LabelFor ...`
  ```

* Last, but not least, using baselines, as discussed
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
